Frequently Asked Questions

Which of my patients are candidates for surgery with the EX-PRESS® Glaucoma Filtration Device? See more

The EX-PRESS® Glaucoma Filtration Device is indicated for open-angle glaucoma patients for whom medication and other conventional surgical treatments have failed, including patients who have previously undergone unsuccessful trabeculectomies.

How does the device's efficacy compare to that of the trabeculectomy? See more

Clinical studies have shown that the EX-PRESS® Glaucoma Filtration Device's implantation procedure effectively maintains steady pressure in the anterior chamber during surgery, and the device's post-op IOP-lowering capability is comparable to the trabeculectomy.1 EX-PRESS® Glaucoma Filtration Device patients also enjoy a decrease in the need for IOP-lowering medication in the long-term, compared with trabeculectomy patients.2

What is Lumenal Control? See more

The Lumenal Control of the EX-PRESS® Glaucoma Filtration Device was developed through extensive research and realized through precise six-point engineering. By filtering aqueous humor flow from the anterior chamber into a subconjunctival bleb through a standardized lumen, the EX-PRESS® Glaucoma Filtration Device yields predictable, repeatable results. Learn more about Lumenal Control.

How does the device's complications rate compare to the trabeculectomy? See more

Not only do EX-PRESS® Glaucoma Filtration device patients experience lower rates of hypotony and choroidal effusion versus trabeculectomy patients,1 but they also average faster recovery rates and fewer post-op visits.3 Read more about the EX-PRESS® Glaucoma Device safety profile.

Have physicians implanting the EX-PRESS® Glaucoma Filtration Device reported any occurrences of corneal decompensation? See more

Corneal decompensation is not an adverse event generally associated with the EX-PRESS® Glaucoma Filtration Device.

How does the EX-PRESS® Glaucoma Filtration Device control postoperative intraocular pressure?See more

Like the trabeculectomy, the EX-PRESS® Glaucoma Filtration Device diverts aqueous humor flow from the anterior chamber to a bleb in the subconjunctival space. Where the methods differ is in the EX-PRESS® Glaucoma Filtration Device's standardized lumen — which maintains uniform aqueous humor outflow — and the dual inlet, which allows for continued drainage even in the event of blockage of the tip.

Is the EX-PRESS® Glaucoma Filtration Device biocompatible?See more

Yes. The device is made of surgical-grade stainless steel, a biocompatible material that has been in use in ORs for more than 30 years. The device has been shown to produce minimal inflammation and scarring.4

Can a patient with an implanted EX-PRESS® Glaucoma Filtration Device safely undergo an MRI?See more

The EX-PRESS® Glaucoma Filtration Device labeling states MRI of the head is permitted, though not recommended, in the first two weeks post implantation. 5

Do surgeons who implant the EX-PRESS® Glaucoma Filtration Device receive reimbursement?See more

Use of the EX-PRESS® Glaucoma Filtration Device is covered by Medicare, as well as most commercial payers.
